I think that by changing the command, you worked around the problem.
the real solution is to look at the syntax of the command "test" which is
written here as "[" and "]"
[ "whatever you want tested" ] is an alternative way of writing test
"whatever you want tested"
now, knowing that the brackets are a command, it is clear that it needs
spaces around the brackets! ("echosomething" is different from "echo
something")
i didn't see any in your original failing commandline.
BTW the final fgrep solution without test is nicer though
Kind Regards,
